Ok, here is the browser test for Ajax Sync Call Freeze Test run by Maxthon developer team.
I run the test with all major browser Firefox, Opera, Internet Explorer and Maxthon (this is not major I guess). The result quite surprising, especially for Firefox the so called greatest browser. Ok, here is the summary of the test result.
1) Maxthon
Browser Version : 2.0.2.2165 Unicode
Result: Pass
2) Firefox
Browser version: 2.0.0.4
Result: Failed - Browser freeze/hang for quite a while
3) Opera
Browser version: 9.21 Build 8776
Result: Pass
4) Internet Explorer
Browser version: 7.0.5730.11
Result: Failed - Freeze for quite a while
My conclusion:
Firefox result failed this pass really surprising me, I think the developer should be aware of something like this furthermore they are open source group that known to be quick responsive to surround. As for Internet Explorer I already guess that it won’t pass. Opera also surprising me, this mean they really serious about their browser and for Maxthon I’m damn sure it will pass even though I’m not using latest version, latest version as for this writing is RC4. Again, why not test your favorite browser against the test, see it will make it or not and would love to hear the result from you in the comment below.
Edit - 16 July 2007
I was mistaken, Firefox and Internet Explorer didn’t freeze completely. They just freeze for some time and complete all the call in the end. Still, I think that is not good because I just test with one tab opened. Imagine if you have 10 or more tab opened, the result would be worse.
